Depth Meter

Guest
While I understand that the depth meter on my explorer is not always accurate...it seems that my meter isn't even close! A coin will be right on top and the meter will show 1/2 blank. Another coin will be at approx. 6" deep and the meter will show that it is on top! I even tried an air test and with the coin 1" from the coil the meter read that it was 6" deep. I am so confused! <IMG SRC="/forums/images/smile.gif" BORDER=0 ALT=":)">
Thanks in advance.
 
I find this too with coins that are 4 inches or less, but after 4 inches it is fairly accruate. I think the one that are the biggest problem are the surface ones as they will give 2 or 3 signals and the depth show 4 or so inches. The large pieces of cans or screw tops will show less than a inch on the surface ones.
I think that most you can tell by the sound of them as to how deep they are unless you have the gain to high and then they will all sound the same.

A few notes to keep in mind on the depth meter: 1) it is calibrated for quarter size targets. So a smaller target will report deeper and a larger target will report shallower. 2) It will report depth on the strongest target under the coil. 3) Shallow targets (3" or less) seem to confuse the Explorer. Simply raise the coil and adjust for the difference. 4) The meter seems to respond much slower than the smartscreen. Many times I can get an ID on a target but not the depth. 5) Air testing is pretty useless with the Explorer. For some reason the Explorer doesn't do very well on air tests or freshly buried coins. But it really eats up the ones that have been in the ground a while. 6) NEVER TRUST THE DEPTH METER. The audio is MUCH more accurate and reliable than the depth meter. I've been blessed to have hunted with some the best Explorer users in this forum and one thing I have heard from pretty much all of them is to always believe the audio on depth over the meter.
I hope this helps. Good luck and good hunting!
 
Awhile back someone posted that the Id on the explorer is a great tool, but they only use it as a reference. The sound was what really keyed them off to what the target was. I know that I will use the screen, but I find myself really trying to hear what the Explorer is telling me.

On my old machine (non Minelab) I used the tone and volume of a target's response to determine its depth. I used to say that I listened for "whispers". With the Explorer, all of my targets sound the same! If there is a target it SCREAMS! Yesterday I dug a very small (size of a pencil eraser) snap at 6" the only time the signal sounded faint was in pinpoint and even then it was only a very slight change!
 
What is your gain set at? If it is set too high then you really can't use audio to determine depth. I leave mine at 7 and everything down to about 4 inches all sounds the same. If you have it set higher than that everything then will probably sound the same. Just a thought.
 
Some say at 4 and some say more, but I run at a 7 for gain as I need all the volume I can get although from surface to around 3 inches sound the same. If you run all the way to 10 than all targets from surface to 10 inchs will sound the same.
